The gram molecular mass of P2O5 is 141.94, and each molecule contains 7 atoms, as shown by adding the subscripts in the formula. 0.400 grams constitutes 0.400/141.94 or about 2.812 X 10-3 mole, and the number of atoms is therefore the product of this number of moles, 7, and Avogadro's Number, or about 1.19 X 1022 atoms, to the justified number of significant digits.
P2O5 2 atoms of phosphorous 5 atoms of oxygen ------------------------------+ 7 atoms altogether
1 P and 5 CI
Mg3P2 contains two atoms of phosphorous.
PbO2 has 3 atoms per formula unit: 1 lead and 2 oxygen.
Two oxygen atoms.
P2O5 2 atoms of phosphorous 5 atoms of oxygen ------------------------------+ 7 atoms altogether
4 atoms of phosphorous 10 atoms of oxygen total = 14 atoms
Carbon can form with oxygen, sulfur, hydrogen, nitrogen, and phosphorous easiest, though it forms many other compounds.
1 P and 5 CI
Mg3P2 contains two atoms of phosphorous.
PbO2 has 3 atoms per formula unit: 1 lead and 2 oxygen.
Phosphoric acid there is 3 hydrogen atoms 1 phosphorous and 4 oxygen the hydrogen has a charge of 1 and the phosphate (PO4) has a charge of 3- so it will look like H- PO4 3-
Two oxygen atoms.
There are 2 Oxygen atoms in CaCO2
Four oxygen atoms.
There are 2 oxygen atoms in dioxide
It depends on how many hydrogens are there and how many oxygen atoms there are.
